AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Saturday, July 27, 2013, 11:11 AM AKDT (Saturday, July 27, 2013, 19:11 UTC)


PAVLOF VOLCANO (VNUM #312030)
55°25'2" N 161°53'37" W, Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Seismicity has remained at low levels over the past 24 hours. Elevated surface temperatures, consistent with cooling lava flows, were detected in satellite data over the past 24 hours, although, views of the volcano in satellite data and in the Cold Bay web camera were often obscured by clouds. It remains possible for eruptive activity to resume at any time and the degree of seismic activity remains above background levels.

VENIAMINOF VOLCANO (VNUM #312070)
56°11'52" N 159°23'35" W, Summit Elevation 8225 ft (2507 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Low-level eruptive activity consisting of lava effusion and minor emissions of steam and ash continues. Nearly continuous, gradually fluctuating volcanic tremor and occasional explosions have been observed in seismic data from Veniaminof Volcano over the past 24 hours. Elevated surface temperatures at the intracaldera cone also have been observed in satellite data. Web camera views from Perryville have been obscured by clouds and fog. AVO has received no other reports of activity at Veniaminof Volcano.



CLEVELAND VOLCANO (VNUM #311240)
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Elevated surface temperatures were detected at the summit of Cleveland Volcano intermittently in satellite data over the past 24 hours. Satellite data suggests that a small lava dome may have developed in the summit crater and may be the reason for the elevated surface temperatures observed over the past week. Views of the summit in the Nikolski web camera have been obscured by clouds and fog. AVO has received no other reports of activity at the volcano.
